Patented Nov. 24, 1936 UNITED STATES PATENT OFFICE My invention relates to a new and improved method of erecting walls of building structures,

interoflice partitions, etc.

In carrying out the improved method it has also been a part of my invention to devise a new and improved wall section.

In carrying out my invention I assemble a wall of a plurality of sections, each section completein itself, of desired thickness, insulating ,10 qualities, height and surface finish. Each section is structurally rigid and is provided with a metallic frame. When the sections are assembled side by side the contiguous metallic frames are locked together by means which extend above and below the frames into the upper and lower supporting members. The upper and lower supporting members are otherwise locked to the sections at the top and bottom, the sections being slid between the upper and lower supporting members as they are assembled in place.

In addition I may provide a novel method of locking the wall sections together by imbedding in each wall section tubular members through which pass extension bolts. Between each pair of sections the extension bolts are provided with clamping nuts which engage the metal frames of the sections as the sections are drawn up in place. Another phase of my invention consists in a new and improved insulating wall section wherein there is used an improved heat and sound insulation.

The objects and advantages of my invention will be best understood from a consideration of the following speciflcationtaken in conjunction 5 with the accompanying drawings, wherein- Figure 1 is a perspective view of a portion of the wall assembly of my improved wall sections and by my improved method of assembly;

Fig. 2 is an enlarged end view, partly in sec- 0 tion, of one of my wall sections showing the assembly at the bottom;

' Fig. 4 is a perspective view of two of the assembly wall sections not mounted in place in the wall;

.Fig. 5 is a cross section on the line 5-5 of Fig.

Fig. 6 is an enlarged view showing in detail the arrangement and assembly using the transverse extension bolts.

Referring to the drawings, II and I2 repre- 56 sent individual wall sections. Each wall section is provided with a. surrounding metal frame 13 which is channeled on all sides as indicated at H. In each section is mounted one or more tubes IS, the tubes being mounted between the channel offsets I4 and terminating in the channels I4. 5 These tubes may be welded or otherwise secured in place, if they are used at all.

The frame I3 is of the depth desired for the wall section and I propose to make the wall formed of my improved wall sections sound and 0 temperature proof by filling the frame with an insulation material which has a certain rigidity and which imbeds the channel offsets l4 and the tubular members IS. The layer of insulation is indicated at 20. 15

For this purpose I provide a new and improved composition insulation which consists in mixing excelsior or similar shavings or chips with a cement-like mortar composed of eighty parts of magnesium oxide, eighty parts of magnesium chloride, and an equal quantity of water, to which approximately thirty parts of powdered asbestos is added. The asbestos powder is added in a quantity to produce theproper consistency.

The excelsior mixed with this mortar is poured into the frame and spread out so as to fill the frame but not extend beyond the edges of the frame. The insulation mixture is then allowed to dry and stay, in which condition it becomes a hard mass filled with innumerable pores and 30 air spaces.

My insulation has a further unique characteristic in that it is moisture-proof. I have found that even immersing the wall section in water will not injure the quality of the insulation and 35 that the insulation will absorb only eleven percent of water. Accordingly, my wall sections are also moisture-proof. p

The wall section may be completed by surfacing one or both sides of the framed section as indicated at l6 and II. For this purpose I may use a mortar or plaster or cement, as it may be termed, composed of the same mixture with which the excelsior is coated except that when used for the outer surface coverings l6 and I1 the consistency will be heavier and will be made so by adding additional powdered asbestos. The surface coverings for the wall sections rest upon the insulation filling and overlie the edges of the frame so that when the wall sections are assembled together a continuous surface is provided asindicated in Figs. 1, 4 and 5.

When a wall is to be erected, top and bottom supporting members are erected in place as indicated in Figs. 1, 2 and 3. There is secured to the foundation 2| a pair of runners 22, 23, which are spaced apart so as to leave a channel therebetween. These runners extend longitudinally of the wall. Over the runners there may be added, if desired, a metallic sheath 24 which is shaped so as to cover the channel between the runners 22 and 23 as clearly shown in Fig. 2. This channel between the runners 22 and 23 correspondsto the channels in the top and bottom of the frames of the respective sections and registers therewith when the sections are assembled in place between the top and bottom runners. A pair of runners 26 and 26 may be arranged atthe top as indicated in Fig. 1 and they are constructed and covered in the same manner as described for the bottom of the wall.

With the runners in place, a wall section 12, for example, is slid into position between the top and bottom runners with the top and bottom grooves of its frame registering with the top and bottom grooves of the supporting members.

. Then a tongue such as indicated at 21 in Fig. 1

is slid into the registering channels between the members 25 and 26 and the channel of the top' of the frame l2 and a similar runner indicated at 28 in Fig. 3 is slid into the registering channels at the bottom, thus locking the frame section [2 in place.

Then before the next section is mounted in place a vertical tongue 29 is placed in the exposed channel of the side frame of the section [2. The tongue 29 is long enough to extend into the channels made by the upper and lower runners. Then the next section, for example section II, of Fig. l is slid into place between the upper and lower runners with the channel of its side frame completing the enclosing of the tongue 29. This is shown to good advantage in Fig. 5. Thus, with the steel frames 13 in close juxtaposition and the tongue 29 looking the frames together and extending into the upper and lower supporting members, the wall is given a strong vertical strut at the intersection of each section of the wall. Additional runners 21 and 28 are fitted in place and this is continued until the entire wall is assembled.

I have provided a further method of locking the wall sections together and of bracing the same which consists of passing through the tubes I5 extension bolts 3| (Fig. 6). Thus, before section ll would be put in place in the above described assembly, the clamping nut 32 of each extension bolt would be screwed home, in which position the nut 32 engages the bottom of the channel H. The vertical tongue 29 is provided with a plurality of transverse holes one of which is indicated at 33 to allow for the clamping nuts 32.

Then when the wall section I l is slid into place, its tubes l5 are aligned with the tubes 15 of the wall section 12 and another set of extension bolts are passed through the tubes l5 of the section II and screwed into the opposite end of the.

clamping nuts 32 so that when the section II is in place the other side of the clamping nuts 32 will engage the bottom of the channel ll of the section II. I have found that this construction gives considerable additional rigidity to the wall, and after the last section is in place the whole section becomes firmly bolted together by the addition of a nut on the outer end of the exposed bolt. The finishing off of the exposed end of the wall, in the case of an omce partition for example, is a simple matter, and the finishing oil! of the inner end of the wall is accomplished by thelnsertion of some filler strips not shown but well known which are then covered over with the same substance as in the surface l6, l1.

After the wall is assembled in place, finishing moldings such as shown at 34, and base boards such as shown at 35, may be put in position.

In Fig. 1 I have shown molded in place in the insulation a switch outlet box 36 and electric cable 31, which is led down to the bottom of the as shown for example in Figs. 1 and 4, thus leaving at the bottom of each wall section a pocket 38 for the passage of electric wires, telephone wires, etc., therethrough, below the level of the base board. For this purpose also, the sides of the frame are apertured as indicated at 39.

In Fig. 3 is shown a modified arrangement to be used when my wall section is used at the outer wall. In this case there is inserted into the base of the frame a lead or other malleable metal strip H which extends out beyond the edges of the frame and the width of the surface covering I6. After the wall section is in place, the strip 4| is bent down over the sides of the supporting runners 22 and along the foundation H to prevent the creeping in and the beating in of rain and water. Where my wall section is exposed to the weather, I find it advantageous to apply a coat of mois ture-proof paint such as asphalt paint, as indicated at 42.

It may be seen from the foregoing that I have not only provided a new and improved wall section, but also a new and improved method of assembling walls so as to present rigid permanent structures.

Modifications may be made in the arrangement and location of parts within the spirit and scope of my invention, and such modifications are intended to be covered by the appended claims.
